Real-time online monitoring technology of large sector lock gate with medium and high water head

针对中高水头三角闸门在运行过程中受力和振动带来的安全性问题,依托引江济汉通航工程龙州垸船闸的三角闸门,采用有限元分析软件ANSYS对其静力特性进行研究,在相应受力最大的位置布置实时在线监测点,利用实时在线监测技术对三角闸门设备性能、运行特性和健康状态实施全过程跟踪和研究。结果表明:对三角闸门主要构件的工作应力、动态特性等开展实时在线监测,是解决闸门结构变形、磨损、振动、缺陷扩展等问题的有效手段,对提高闸门运行安全、保证其功能的正常发挥十分重要。

Given the safety problems caused by the force and vibration during the operation of the medium and high water head sector lock gate,we combine with the sector gate in Longzhouyuan ship lock of the river diversion project from the Yangtze River to the Hanjiang River,study the static characteristics of the sector lock gate by using the finite element analysis software ANSYS,arrange the real-time online monitoring points at the corresponding maximum stress position,and apply real-time online monitoring technology to track and study the whole process of the performance,operation characteristics and health status of the triangular gate equipment.The results show that the real-time online monitoring of the working stress and dynamic characteristics of the main components of the sector gate is an effective means to solve the structural deformation,wear,vibration,defect expansion,and other problems of the gate,which is very important to improve the operation safety of the gate and ensure its normal function.
